BICYCLE-LAMP BRACKET.

SPECIFICATION forming part of Letters Patent No. 600,642, dated March 15, 1898'. Application filed July 14:, 1897. Serial No. 644,483. (No model.)

To all whom it may concern:

Be it known that I, NOBLE W. HARTMAN, a citizen of the United States, residing at Toledo, Lucas county, Ohio, have invented certain new and useful Improvements in Bicycle-Lamp Brackets, of which the following is a specification.

My invention relates to and its object is to provide a bracket for bicycle-lamps, which shall be cheap, simple, and durable and which will admit of the vertical and lateral adjustment of the lamp to any desired angle. I attain these objects by means of the device hereinafter described and shown, and illustrated in the accompanying drawings, made part thereof, in which Figure 1 represents a top plan view of my bracket with a lamp attached; Fig. 2, a side elevation of the same without the lamp; Fig. 3, a front elevation of the piece by which my bracket is connected with the lamp, serving also as a reflector-holder; Fig. 4, aplan view of one of the plates or arms hereinafter referred to detached, and Fig. 5 a plan elevation and side elevation of another of the plates hereinafter referred to.

Like letters and figures of reference indi cate like parts throughout the several views.

In the drawings, AA are two strips of metal, preferably sheet metal, stamped or pressed into shape from a flat blank, both pieces being alike. At one end each of the plates or arms A is formed into the segment of a hollow sphere y. These parts of the two plates A, when brought together face to face, form nearly a complete hollow sphere. Vertically through the sphere thus formed is cut an opening 1, which may be enlarged, or may resemble two cuts at right angles to each other, as shown. Through the two arms A are horizontal holes 2 and 3, designed to receive bolts and nuts adapted to clamp the two plates upon the bicycle and in adjusted relation to each other. In the end of the plates opposite the cup-shaped ends are bends 44, which together form a recess the shape of a bicyclefork in cross-section. Between the two extremities of the plates are also larger bends 5, which together form a recess or opening adapted to fit a bicycle-head.

B B are cup-shaped pieces formed, prefervertically and centrally through both of said pieces and through openings 1 in the spherical parts y of the arms A. To prevent loss of the bolt or nut, the nut for the bolt 6 is brazed, as at 6?, (see Fig. 2,) upon the lower cup B. The cups B are provided with extensions I), having ears or flanges 13.

O is a strip of sheet metal, or, rather, three integral strips, two horizontal strips united byavertical strip. The horizontal strips are curved to conform to the contour of the cylindrical interior of the lamp-body 12.. The extremities of the horizontal strips just referred to are bent inwardly, as at 9 and 10, forming a slide, into which may be slipped the reflector. The vertical portion of the piece 0 has backwardly-turned flaps 11 11, which project through the lamp-body 12. The extensions 1) of the cups B fit between the flaps 11, and through these flaps and through the flaps or ears 13 of the cup-shaped pieces B are holes through which pass horizontal pins 8. The two cup-shaped pieces B are each pivoted upon one of these pins.

The operation of my device is as follows :v

Assuming that the cups B are pivotally secured to the projecting flaps of the reflectorholder with the cupped openings toward each other, one above the other, thatthe spherical part formed by the extremities of the arms A are clasped between the cups B, that the bolt 6 passes vertically through the two cups B and through the spherical portion 3 and is screwed loosely into nut 6 the arms A may now be spread slightly apart and may be moved past each other vertically. This permits the bent portions forming the recess 5 to be slipped over and to clasp the bicyclehead. The bolt 7 is now passed through the holes 2, and by means of its nut the arms are clamped tightly in place. The lamp is now moved horizontally and vertically into the required adjustment. It will be seen that the two caps B slide upon the exterior of the pieces y and that the enlarged openings 1 permit the swing of the bolt 6 at an angle either forwardly, backwardly, or to the right or left. The lamp being set at the desired position, the bolt 6 is screwed. tightly into its nut 6, the cups B are caused to tightly clasp the ball y, and the lamp is now held rigidly upon its bracket and upon the bicycle.

If it is desired to clamp the bracket to the fork, it is accomplished as above described, the bolt 7 being passed through the horizontal holes in the arms A next to the recess 4.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a bicycle --lamp bracket, two arms adapted to clamp between them suitable portions of a bicycle, hollow hemispherical portions on each of said arms disposed relatively to each other approximately as a sphere and having axially therethrough an enlarged opening, two cup-shaped pieces adapted to clamp between them said hollow sphere, connections intermediate said cup-shaped pieces and the lamp, and a clamping-bolt passing through said cup-shaped pieces and through said enlarged opening, whereby said cups may be swung relatively to said sphere in any desired direction and whereby said cups may be clamped in adjusted position.

2. In a bicycle lamp bracket, two arms adapted to clamp between them suitable portions of a bicycle, hollow hemispherical portions on each of said arms disposed relativelyto each other approximately as a sphere and having axially therethrough an enlarged,

vertical opening, a top cup-shaped piece, a
